Endovascular intervention to treat severe limb ischemia

1. What is severe limb anemia?

Severe limb ischemia is a severe blockage of an artery, reducing blood flow to the extremities (arms, legs, and feet) causing pain and soreness.

2. Causes of severe limb anemia

The cause of severe limb ischemia is a sudden rupture of one of the large arteries supplying the extremities, causing the patient to have lower limb ischemia. Due to an injury that causes an artery injury or an artery blockage due to a blood clot, or a foreign object entering from another place, the artery is blocked. The limb ischemia is classified into 3 levels: acute limb ischemia, chronic limb ischemia and subacute limb ischemia.

3. Signs of severe limb anemia

Severe ischemic disease often begins with a stroke. Foot ulcers, infections or ulcers that do not heal or heal very slowly. Feeling of numbness in hands and feet, reduced sensation on the extremities, cold extremities. After a while, pain in the extremities and gradually lost sensation in the extremities, more seriously, led to limb necrosis.

4. What is endovascular intervention for severe limb ischemia?

Currently, with modern technology and medical development, for patients with severe limb ischemia, doctors will perform endovascular intervention to treat severe limb ischemia. This is a new method to effectively treat severe and complicated injuries with anemia, and the method brings high safety, without surgery.
The method of endovascular intervention (English name: Subintimal technique) is a subendothelial dissection that was first applied in 1987. Currently, this technique has been improved, developed and applied. Widely used to treat patients with lower extremity artery occlusion.
Endovascular intervention method is both effective and has a high success rate. However, this is a complicated method, vascular occlusion - the main cause of severe limb ischemia usually occurs on a long segment of the vessel, while the human vessel wall is very thin, very easily broken during the procedure. devices outside the circuit. Therefore, it is required that the doctor or the person performing the method must have high expertise and skills to skillfully manipulate the procedures and approach the system, which can be accurately evaluated.

The doctor inserts a catheter into the radial artery of the arm or in the femoral artery to create a path for the interventional instruments to enter the artery. After the procedure is completed, only a small hole is left in the skin. Bandage the incision with special instruments for about 12 hours (for the radial artery) or up to 24 hours (for the femoral artery). During that time, the patient should minimize movement such as bending and stretching at the incision to avoid bleeding.

5. Notes after endovascular intervention to treat severe limb ischemia

After about 1 to 2 weeks of rest, the patient can walk and work normally. However, the patient should pay attention:
Limit going up and down stairs to avoid having to bend and flex the limb. Short walk. Do not do heavy work to avoid putting pressure on the bones. If the incision to insert the catheter is bleeding or swollen, the patient should lie down, apply pressure to the wound for 30 minutes to stop the bleeding. Drink a lot of water (except for people with severe heart failure), eat a lot of green vegetables, fruits, don't drink alcohol, stimulants, tobacco, etc. Do gentle exercises. Follow up with the doctor on time. request.
